IMPROVEMENT IN SLAG-POTS FOR USE AT SMELT lNG-FURNACES.

Specification forming part of Letters Patent No. 131,868, dated October1, 1872.

To all whom it may concern:

Be it known that I, ROBERT A. FISHER, of

Eureka, Lander county, State of Nevada, have invented Improvements inSlag-Pots; and I do hereby declare the following descriptionandaccompanying drawing are sufficient to enable any person skilled in theart or science to which it most nearly appertains to make and use mysaid invention or improvements without further invention or experiment.

My invention relates to an improvement in that class of pots used aboutsmelting-furnaces, which are known as slag-pots. These pots are used forreceiving the slag as it comes from the furnace, and are consequentlysubjected to an extremely high temperature, by which the iron issuddenly expanded, rendering them liable to crack, split, or break, andfrequently they are broken from other causes The expense of these potsis quite an item, where large smeltingworks are conducted, on accountiofthis breakage. My invention con- .sists in constructing these slag-potsin sections, and then unitingthe sections by proper means, so that incase one of the sections should become cracked, split, or broken it canbe readily replaced with a new section at a composite projectionstogether, and thus complete.

the pot.

Various clamping arrangements can be applied to fasten the sectionstogether, any of which will answer my purpose.

It is evident that a slag-pot thus construct ed will be much moreeconomical than those constructed in one solid piece;

Having thus described my invention, what' I claim, and desire to secureby Letters Patent, is-

A slag-pot, or equivalent pot or kettle, constructed in two or moresections, in the manner and for the purpose above described, as a newarticle of manufacture.

i In witness whereof I hereunto set my hand and seal.
